This works fine for me; look at your options on 'scan':
> x <- scan(text = "H20100902.TXT
+ H20100903.TXT
+ H20100904.TXT
+ H20100905.TXT
+ H20100906.TXT
+ H20100907.TXT
+ H20100908.TXT", what = '')
Read 7 items
> cat(x, file = 'file.txt', sep = '\n') # create the 'file.txt'
>
> files <- scan('file.txt', what = '') # read names from the file
Read 7 items
> files # display the names
[1] "H20100902.TXT" "H20100903.TXT" "H20100904.TXT" "H20100905.TXT"
"H20100906.TXT"
[6] "H20100907.TXT" "H20100908.TXT"
